DUST SEPARA'IING AND COLLEG'EING APPARATUS. i

Specification of Letters Patent.

tion of the inventigm, sueh us will enable othersslulled 1n the art to which it uppertoins to inuke and use the some.

My invention relates to dust eolleetois l'or mills and simihu plants where it is desired to convey the heated nil from the mill and. to se 'iai'utennd eolleet the dust nnd other solid matter in the air. I l

The object oi" in) invention. is to pro'rirh-l :1 simple construction,which is ell'eetive in its operation and. which may be adjusted to suit varying drafts and eonditions of the air, and

which may be easily applied to ordinary forms of stocks.

My invention consists of the construction, eonlbimitioi'i and ntrrangement of ports, as herein illustrated, deseribed and cleimed.

1n the aeoompzmying drawings, forming part of this application, .l have illustrated one/form of embodiment of my inw-uition, in

which drawings similar rel'erenee elmreeters designate corresponding ports, and in which: Figure 1 is a. central vertieel section, portly in elevation; Fig. 2 is it horizontal section taken zipproxilnnte 5m line 2--2 of Fig. 3, looking in the direc ion indies ,ed by the row; end, Fig. 15 is it horizontal seotion taken approximately on line il--;l of .l ig. 1, looking in the direction indieuted by the arrow.

:lteferring to the drawings, 1 designates it stock, on the upper end oi which is disposed a casing 2, the lower well of which is inelined towards its eenter.

Secured to the inner wall of the easing 2, is a plurality oi" lRtWlil 1s 3, adapted to reeei've angle irons l, towhieh angle irons secured the inwardly projecting flange 5 of it hell 6, which bell is disposed entirely within the easing 2, so as to leave. a. space 7 between its lower edge and the will of the nsisg This spoee is lel't so as to permit a d rzd't upward through the easing, end the well oi the hell (3 is inclined downward and outward, so that any solid nntteriul 'whieh posses allow the bell will tell thereon and he directed downu hired.

nerd and outwerd against the wall of the casing. Slidobly disposedon the upper end of the stack 1, below the hell 6, is a sleeve 8, on which is mounted rollers 9, adapted to receive flexible members 10, which flexible memhers support the sleeve 8. One end of the flexible nwn'ilnnis secured to cleats 11 on the inner well of the casing 2, and the opposite ends of the flexible members are disposed through openings 12 in the Wall of the casing '3, and are provided with handles 13. Brook ets 14- are, secured on the outer Wall of the easing .3 adjacent the openings 12, and have disposed thereon rollers 15, adopted to reeeive the flexible men'ihers 10, so that they may he easily moved. By pulling on the handles 13, the flexible members will he tightened to raise the sleeve 8, and thereby vary the distance between the upper end of the stuck and the lower face of the hell 6. so that the draft throughthe stock. and the easing 2 is varied to suit the conditions rettlolid matter in the air passing through the. sleek 1 will strike the under surl'nre of the hell (i, and will be deflected down ward therein, and will fall to the hottom of the e: ring 1?.

i For the purpose of conducting the matter from the easing 2, tubes 16 are. connected to the loner end thereof, and in turn are joined to n. diselnu'ge pipe 17, the lower end which has at pivoted closure 18, \Vllit'l'l prevents e. book draft through the pipes 16.

lrojerting u ithin the casing 2 from its upper end, is an air exhaust pipe 19, which is surmounted by a. hood 20 of common eon,- struetion. Slidnhly disposed on thelower end of the pipe 19, within the easing M 1, is :l-I sleeve 21, provided with a. lower outnerdlyj.

site ends enrried through openings .26 in said well. 'lhe outer ends of the ilexihle members 24- :tre. provided ilh handles, 37,8.11d are disposed over rollers 23, enrried on hrucltets 2.) on the outer well of the using 2, so that the llexible members 24 may be easily moved.

ily pulling on the handles 2'7, the sleeve 21 Sill llltl between the lower surface of the flange 22.

will be elevated so as to increase the distance and ti e upper surface of the bell 6, that the draft through the exit pipe 19 maybe varied to suit gliflerent conditions.

For the purpose of providing a structure which is easily removable, the casing 2 is rei erably made in two sections, which may easily joined together by means of angle iron, members 30, which angle irons may be riveted to the sections of, the casing 2 and may be riveted together.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

l. A collector and separator comprising the combination of a stack, a casing on the stack brackets secured tothe inner wall of 'the casing, a flanged bell secured on the brackets, gneans for varying the space between. the stack and the bell, an exit pipe projecting into the casing from its upper end,

- means for varying the spacebetvveen the stack within the casing,

I pipe and the exit pipe and the bell, and means for conducting separated matter from the casing.

2. A collector and separator comprising the combination of a stack, a casing on the stack, a sleeve movably disposed on the means for raising the sleeve, a bell fixed above the sleeve, an exit pi e projecting into the casing above the bel and means for varying the space between the exit pipe and the bell.

3. A collector and separator comprising the combination of a stack, a casing on the stack, a sleeve movably disposed on the stack Within the casing, rollers on thesleeve, flexible members having one of their ends fixed and their opposite ends disposed throngh the wall of the casing so that intermediate of their ends the flexible members pass under the rollers, a bell fixed above the sleeve Within the casing, an exit pipe projecting into the upper end of the casing, and means for varyirlilg the spacebetween the exit e 4. A collector and separator comprising the combination of a stack, a casing on the stack, a sleeve movably disposed on the stack within the casing, rollers on the sleeve,

flexible members disiposed under the rollers nd having one 0 their ends disposed through, openings provided in the wall ofthe casing, cleats secured on the inner wall of the casing, to which cleats are secured one of the ends of the flexible members, brackets secured on the outer wall of the casing, rollers on the brackets over which the outer ends of the flexible members are disposed, a bell iixed within the casing above the sleeve, aniexit pipe extending within the up per end of the casing, and means for varying the space between the lower end of the exit pipe and theb'ell.

collector and separator comprising the combinationof a stack, a casing on the stack, a bell lixed above the stack within the casing, means for varying the space between the bell and the stack, an exit pipe arranged on the casing abovethe bell, a sleeve slid ably disposed on the lower end of the exit pipe and provided with a downwardly inclined flange, and means formoving the sleeve on the exit pip'e.

' 6. A collector and separator comprising the combination ol a stack, a casing on the stack, a bell fixed above the stack within the casing, means for varying the space between the bell and the stack, an exit pipe arranged on the casing above the bell, a sleeve slidably dis osed on the lower end of the exit pipe and provided Hvith a downwardly inclined 'flange,-rollers on the sleeve, flexible members having their ends iixcd within the casing disposed under the rollers and projecting from the casing, and friction reducing members disposed under the flexible'members outside of the casing.

7. A collector and separator com )rising the combination of astack, a casing ormed of two parts and disposed on the stack, angle iron members connecting the two parts of the casing, a bell in the casing above the stack, means for varying the distance between the stack and the bell, an exit pipe projecting into the top of" the casing, and means for varying the distance between. the exit pipe and the bell.

In witness whereof I have hereunto set my hand in the presence of twowitncsses.
